Astra C18-AQ

ASTRA® HPLC columns extend our ARION® and CHROMSHELL® product lines.

ASTRA® HPLC columns extend our ARION® and CHROMSHELL® product lines. The ASTRA® has been developed in the Czech Republic to offer an alternate to a broad range of general HPLC columns. ASTRA® brings completely new and unique stationary phase with the polar embedded group to offer a complementary selectivity.

  • Unique and different endcapped C18 phases.
  • 330 m2/g surface area.

Main particle characteristics

  • Close proximity to a sphere.
  • Highly effective, mixed, proprietary endcapping.
  • No broken particles.
  • Robustness to high pressures.
  • Lot-to-lot reproducibility.
  • Unique modern embedded phases.

ASTRA® column hardware

  • Electropolished with very low Ra reduces wall effect
  • Rated up to 20000 psi (1300 bar), ideal for the UHPLC applications
